BRICK-MACHINE srncrrrcarrolv forming para of Letters Patent No. 649,792,dated May 15, 1900.

Application tiled September 9, 1899. Serial No. 729,941. (No model.)

To all whom, it may concern:

Be it known that I, RUSSELL ANTHONY, of lVortham, in the county ofFreestone and State of Texas, have invented a new and ImprovedBrick-Machine, of which the following is a full, clear, and exactdescription.

One object of the invention is to provide an effective, yet simple anddurable, machine especially adapted to receive bricks from a stiff-mudmill and re-press them and also to provide a means whereby the machinewill be automatic in its action.

Another object of the invention is to so construct the machine that thebricks to be treated will be fed to the machine by a snitable conveyerand conducted one after the other to the press box, released from thepressure of the box and its follower, and removed from the box to asecond conveyer, which will conduct the finished bricks to any desiredpoint.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth,and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of theimproved machine, illustrating thefollower in position to force the finished brick from the press-box andcarry a second brick into the said box. Fig. 2 is a bottom plan view ofthe body portion of the machine. Fig. 3 is a rear elevation of themachine. Fig. 4 is a horizontal section taken practically on the line etet of Fig. 1. Fig. 5 is a central vertical section through the machine,the follower being shown in position to receive a brick to be pressed,having carried one of said bricks into the press-box. Fig. G is anenlarged sectional view taken practically on the line G 6 of Fig. 1,illustrating the manner in which the sides of the press-box are renderedadjustable; and Fig. 7 is a partial plan view and partial sectional viewof one of the pitmen employed in the movement of the follower of themachine. The frame of the machine consists of a table 10,supporting-sides 11 for said table, and a supporting-back 12, the saidsupportingback having an opening 13 extending through box C, to behereinafter described, nearly out through the forward end of the tablel0. Parallel plates 15 are secured on the upper face of the table 10,one at each side of the center of the table, as shown in Fig. Ll, andthese plates are at each side of the slot 14 of the table, extending thelength of said slot outward beyond the forward end of the table. Thespace between the plates 15 constitutes a slideway A for a follower 25,to be hereinafter described. The extended portions of the plates 15 haverollers or drums 18 19 journaled between them, which drums or rollerscarry an endless conveyer-belt 20, adapted to travel in direction of thetable, and a suitable guide-partition 21 is located between thestretches of said belt 20. One of the drums or rollers 18, preferablythe inner roller, has a shaft 22, that extends to one side of the table,as shown in Fig. f1, a suitable guide 23 being provided, and this shaft22 carries a pulley 24 at its outer end. A top plate 17 extends from oneside plate 15 to the other at the forward portion of the table, and saidtop plate constitutes a cover for a portion of the slideway A. This topplate 17 is practically of a length corresponding to the length of thefollower 25, hereinafter referred to, since when the follower 25 is inits initial position in the slidewa7 A it will be beneath this top plate17, as indicated in dotted lines in Fig. Ll. The follower 25 is adaptedto receive bricks B, fed from the mill or other source of supply throughthe medium of the conveyor 20, said bricks B being forced lengthwise ofthe cover-plate 17, as shown in Fig. 5, and when the follower 25 has itsforward end only beneath the cover-plate 17 the movement of the bricksis so timed that one of said bricks will be received upon said follower,and at the forward movement of the follower the said brick will beforced therefrom into that portion of the slideway A occupied by thefollower in its rearward position, so that at the next forward movementof the follower, if a brick be in the press-box, the brick in theslideway, which is the next brick to enter said.

IOO

ian

box, will force the brick in the boX out therefrom as the follower againmoves forward, the press-box being then in suitable condition to permitthe free exit of the pressed brick, as will be hereinafter described indetail. The follower 25 is guided in its movement by a fin 26, thatextends from lits bottom through the slot 14 in the bed or table 10 ofthe frame, as is best shown in Fig. 5.

A slide 27 is mounted to have vertical movement in suitable ways 28,located on the back 12 of the frame, as shown in Fig. 3, and this slidewhen in its upper position constitutes the rear end of the press-box C,the bottom of the said box being the rear end portion of the table 10,as is also shown in Fig. 5. The sides of the press-box are adjustable toand from each other and consist of plates 29, unattached to the table;but each side plate 29 at its center is provided with an angle-iron 30,as shown in Figs. 3, 4, and 6. The horizontal member of each angle-ironis mounted to slide over a transverse slot 3l made in the table 10, andeach slot 31 is in communication with a lower and wider slot 32 produceddirectly in the sides of the table, as illustrated in Figs. 1 and 6. Thehorizontal member of each side plate 29 of the press-box is providedwith a T-shank 33, (shown in detail in Fig. 6,) the vertical member ofwhich moves in the slot 31 and the horizontal member below the table,and this horizontal member maybe projected outward through the slotextension 32, when so desired, to carry the side pieces or plates of thepress-box quite far apart.

A bracket 34 is located above the outer end of each slot 31, and eachbracket 34 is connected with a side plate 29 of the press-box C by ascrew 35, and each screw is provided with a right-hand thread at one endand with a left-hand thread at the opposite end. Each screw is furtherprovided with an arm 36, since when the slide 27 is dropped, as shown inFig. 3, to permit the outward passage of a pressed brick the downwardmovement of the slide automatically causes the sides of the press-box tomove in opposite directions, thus freeing the side portions of thepressed brick. This is accomplished by connecting the rear ends of thearms 36 with the bottom side portions of the slide 27 by means of links37, as shown in Figs. 3 and 5, suitable lugs 38 being provided to thatend at the lower portion of the slide. The rear end of the follower 25when the follower is in its rearward position constitutes the forwardend of the press-box.

A plunger D is adapted to enter the pressbox and re-press or compressthe brick contained therein, and said plunger is operated by thefollowing mechanism.

A standard 39 is secured on the table at each side of the press-box C,and these standards are preferably rearwardly curved at their upperends. The standards are provided at their forward edges with bearings,in which a shaft 40 is journaled, the shaft hav-inga crankarm 41 aboutcentrally between the standards, and at one end of the shaft a pulley 42is located, which is connected by a belt 43 with the pulley 24 of theconveyer 20, and the shaft 40 at the same end is provided with a gear44, adapted to be rotated by mechanism to to be described farther on inconnection with the actuating mechanism of the follower 25. The plungerD is connected with an upwardly-'extending plate 46, widest at the upperportion, and this plate is adapted to slide in ways 47, 'extendinginwardly from the rear edges of the standards 39, as shown in Fig. 3.The plate 46 is also preferably provided with a central longitudinalboss 46, andv links 47 are pivotally attached to this boss, as shown inFig. 3, being connected at their upper ends by a suitable pivot-pin 48.On this pin, between the links, the upper bifurcated portion of a pitman49 is pivoted, the lower portion of said pitman 49 being connected withthe crank-arm 4l of the shaft 40, and a link-arm 50, likewise mountedonthe pin 48, is pivotally attached to the upper central portions of thestandards 39, as shown in Figs. 3 and 5. Thus it will be observed thatby the rotation of the shaft 40 and the connection between this shaftand plunger the plunger is raised and lowered and when lowered may bemade to tightly press any object in the press-box.

The main driving mechanism consists of a shaft 51, journaled in theframe of the machine below the table 10. This shaft 51 carries a gear 52at one end, which meshes with the gear 44 on the upper shaft 40, and theshaft 5l at .the same end likewise carries a pulley 53, adapted for beltconnection with any source of power. A crank-arm 54 is formed at thecentral portion of the shaft 51, as shown particularly in Fig. 5, andthe rear end of a pitman 55 is pivotally attached to the crank-arm 54,while the forward end of the pitman 55 is forked, as shown in Fig. 2,and the forked end of the pitman is pivotally connected with thedownwardly-extending member of an angle-lever 55a, fulcrumed to theunder side of the table, usually near the forward end of the slot 14therein, while the other member of the angle-lever 55a is pivotallyconnected by links 56 with the fin 26 of the follower 25. The pitman 55is provided with the fork above referred to in order that the links 56may have free downward movement as the crank-arm 54 is carried in aforwardly direction, as shownk in Fig. 1, and when the crank-arm iscarried in this direction the follower 25 will be within the coveredportion of the slideway A. When the crank-arm 54 extends horizontallyrearward, the follower 25 will be in position to form the forward wallof the press-box C, and as the crank-arm descends the slide 27 being inthe lower position shown in Fig. 3 said crank, arm will carry the slideup to form the rear wall of the press-box, as shown in Fig. 5, holdingit in this position until the plunger D IOC has operated to press theVbrick beneath it.

This movement is accomplished by moving a lever 57 upon a fixed shaft58, the forward end of the lever being in the path of the crankarm as itdescends, and the rear end of the lever is connected by a link 59 withthe back of the slide 27 through the medium of an extension 60. Thus itwill be observed that the slide 27 will be held in position to form aportion of the press-box as long as the link 5a engages with the lever57 and that when the slide 27 is raised the arms 3G are carried upwardand the sides 29 of the press-box are brought to a proper position. Whenthe crank-arm 5l is released from the lever 57, the slide 27 will dropby gravity,or especial means may be provided for carrying it downward,but as the slide travels downward the arms 3G, connected with the screws35, are drawn in the same direction, and the sides of the press-box aremoved in direction of the sides of the bed, thus leavin g the pressedbrick free.

In operation let it be supposed that one brick is in the press-box andanother brick is in position to enter the box, the follower engagingwith the forward end of the second brick or is in its normal positionshown in Fig. l. It will be remembered when the follower moved forwardto its normal position the slide 27 dropped and the sides of thepress-box were carried outward. At the next or rearward movement of thefollower said follower will force the second brick against the one inthe press-box, thus forcing the pressed brick out from the box, thesecond brick taking its place and the pressed brick E being receivedupon a suitable conveyer E at the rear of the machine. Just prior to thefollower reaching the forward end of the pressbox the crank-arm 54C willhave acted upon the lever 57 and brought the parts of the box to theirclosed or molding position and the plunger will have descended andpressed the brick beneath it. At just about this time the rearmost brickl5 in the chain of bricks to be compressed will have been forced fromthe plate 17, covering the slideway A, upon the upper surface of thefollower, and as the follower moves rearward and the parts of thepress-box are also moved to release the pressed brick the next brick tobe pressed and now carried by the follower will slide therefrom into theslideway as the follower is carried beneath the said covering-plate 17.

In Fig. 7 I have illustrated a slightly-modified form of the rear end ofthe pitman 55 or that end which is adapted for engagement with thecrank-arm 54, and in this modified form of pitman 55 a closed yoke Gl isformed at its rear end, in which a box 62 is mounted to slide, made intwo sections, and one of these sections is controlled through the mediumof a spring 63, located within the yoke and bearing against said sectionand against the inner end of a set-screw G4, carried by the rear endportion of the said pitman. In this manner the boxes G2 may be made tolit lthe crank 5l more or less snugly and friction is reduced to aminimum.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a brick-press, a press-box having movablecoperating parts, mechanism for shifting the side parts to and from eachother, means adapted to move an end part of a box in a path at an angleto the path of the side parts, a device for supplying the box withmaterial, and a mechanism for actuating said device, arranged to controlthe combined shifting mechanism.
